I am new to bash scripting. i had tested a basic script eg. script.sh and it get executed. But it also gives an output "./script.sh: line 1: #!/bin/bash: No such file or directory"

How to resolve this. Plz help

apparently bash is not installed in /bin
do a 'which bash'
and update accordingly

For example:
which bash
gives the answer
/usr/bin/bash

then the shebang (1st line) would be:
#!/usr/bin/bash

Of course, it's also possible bash is not installed, in which case you will get that as answer from which; it would be interesting to see what shells are available.

The following command might help on that: echo $SHELL
It should give you an indication on where your shell is located.
